The BOSS RC-505MKII Loop Station is designed to handle multiple tracks simultaneously, offering a versatile platform for creating complex and layered musical compositions. Here’s how you can use multiple tracks with this pedal:

The RC-505MKII supports up to five simultaneous stereo phrase tracks. Each track functions independently, allowing you to record, play, overdub, and manipulate audio on each track separately. This is particularly useful for creating loops with different instruments or vocal parts.

Each phrase track has dedicated controls, including volume faders, Input FX, Track FX, and customizable FX buttons. These controls enable you to adjust the volume, apply effects, and trigger different actions for each individual track.

To start recording on a specific track, select the desired track and press the record button. You can record your audio input, whether it’s vocals, instruments, or any other sound source, onto the selected track. Each track can have its own unique content.


After recording a phrase on a track, you can overdub additional layers on the same track by pressing the overdub button while the track is playing. This allows you to build up complex musical arrangements by adding new parts or harmonies to your loops.

Once you have recorded content on multiple tracks, you can start and stop each track independently. This gives you full control over when and how each track plays back, allowing for dynamic arrangements and live performances.

The pedal provides options to mute and clear individual tracks, giving you the flexibility to remove specific elements from your composition or make room for new recordings.

The RC-505MKII features a built-in metronome and tap tempo function to help you keep all your tracks in sync. This ensures that your loops maintain proper timing and rhythm, even when working with multiple tracks.
